See explaination
Explanation:
a)
The primary factors that influence the program's speed on a new CPU are given as:-
CPU Clock speed where the speed of the process instructions is being measured.
Multi-core which is when the transistors work faster than respective CPU.
Cache which helps to note that the transition of data is smooth and fast.
b)
So, there are two CPUs suppose the old one as 'A' and the modified one as 'B'.
'A' has following features---
It takes more time to execute program as it has more clock cycle time or we can say it has low clocking rate or low speed in terms of MHz or GHz. Clock rate is the inverse of Clock Cycle Time. When you will increase the clocking rate of CPU, it will get faster and then Clock Cycle Time will get reduced.
It has less instructions provided.
'B' has following features----
It takes less time to execute program as it has less clock cycle time or we can say it has high clocking rate or high speed in terms of MHz or GHz.
It has more instructions provided.
The performance of CPU depends upon 2 factors:
The number and types of instructions that are executed by the CPU
How fast the CPU can execute those instructions?
So, overall CPU B is better as it has less execution time than CPU A but the performance will always depend upon the number and type of instructions executed by the CPU so it may vary.

Answer:
Follows are the modified code in c++ language:
#include<iostream>//header file
#include<string>//header file
using namespace std;
int main()//main method
{
string name,address, MSG_YES, MSG_NO;//defining string variable
int item,quantity,size=6, i=0;//defining integer variable
double price;//defining double variable
int VALID_ITEM[]={106,108,307,405,457,688};//defining integer array and assign value
double VALID_ITEM_PRICE[]={0.59,0.99,4.50,15.99,17.50,39.00};//defining double array and assign value
bool foundIt=false;//defining bool variable
MSG_YES="Item available";//use string variable to assign value
MSG_NO = "Item not found"; //use string variable to assign value
cout<<"Input name: ";//print message
cin>>name;//input value in string variable
cout<<"Input Address: ";//print message
cin>>address;//input value in string variable
cout<<"Input Item: "<<endl;//print message
cin>>item;//input value in string variable
cout<<"Input Quantity: "<<endl;//print message
cin>>quantity;//input value in string variable
while(i <size)//defining while that checks i less then size
{
if (item ==VALID_ITEM[i]) //use if block to match item in double array
{
foundIt = true;//change bool variable value
price = VALID_ITEM_PRICE[i];//hold item price value in price variable
}
i++;//increment the value of i
}
if (foundIt == true)//use if to check bool variable value equal to true
{
cout<<MSG_YES<<endl;//print value
cout<<"Quantity "<<quantity<<" at "<<"Price "<<price<<"each"<<endl;//print value
cout<<"Total"<<quantity*price;//calculate the total value
}
else//else block
cout<<MSG_NO;//print message
}
Output:

Explanation:
In the above given C++ language modified code, four-string variable " name, address, MSG_YES, and MSG_NO", four integer variable "item, quantity, size, and i", and "integer and double" array is defined, that holds values.
In the string and integer variable "name, address, and item, quantity", we input value from the user-end and use the while loop, which uses the if block to check the "item and quantity" value from the user end and print its respective value.
